Java - 将字符串转换为有效的URI对象 [英] Java - Convert String to valid URI object

问题描述

我正在尝试从 String 中获取一个 java.net.URI 对象。该字符串具有一些字符，它们需要由其百分比转义序列替换。但是当我使用URLEncoder对UTF-8编码的字符串进行编码时，即使使用/代替它们的转义序列。

I am trying to get a java.net.URI object from a String. The string has some characters which will need to be replaced by their percentage escape sequences. But when I use URLEncoder to encode the String with UTF-8 encoding, even the / are replaced with their escape sequences.

如何获取有效的编码URL String对象？

How can I get a valid encoded URL from a String object?

http：// www.google.com?q=a b 给出了 http％3A％2F％2www.google.com ... ，而我希望输出为 http://www.google.com?q=a%20b

http://www.google.com?q=a b gives http%3A%2F%2www.google.com... whereas I want the output to be http://www.google.com?q=a%20b

有人可以告诉我如何实现这一点。

Can someone please tell me how to achieve this.

我在Android应用中尝试这样做。所以我可以访问有限数量的库。

I am trying to do this in an Android app. So I have access to a limited number of libraries.

推荐答案

您可以尝试： org.apache。 commons.httpclient.util.URIUtil.encodeQuery 在 Apache commons-httpclient 项目

像这样（见 URIUtil ）：

URIUtil.encodeQuery("http://www.google.com?q=a b")

将成为：

http://www.google.com?q=a%20b

你当然可以自己做，但是URI解析可能会变得很混乱...

You can of course do it yourself, but URI parsing can get pretty messy...
